Lack of virulence factors in Escherichia coli strains of enteropathogenic serogroups isolated from water.
Thirty-eight Escherichia coli strains belonging to 14 human enteropathogenic serogroups were isolated from 33 of 208 water samples studied. No virulence factor or virulence-related gene sequences were found in any of the 38 strains analyzed. The results point out the importance of detecting specific virulence factors before incriminating water as a source of human diarrhea.
متن کاملCharacteristics of Escherichia coli strains belonging to enteropathogenic E. coli serogroups isolated in Italy from children with diarrhea.
Fifty-five Escherichia coli strains belonging to enteropathogenic E. coli (EPEC) serogroups were examined for phenotypic and genetic factors associated with virulence. The strains were isolated in Italy from children with diarrhea and identified as EPEC by clinical laboratories using commercially available antisera. O:H serotyping showed that 35 strains (27 of O26, O111, and O128 serogroups) be...
متن کاملMolecular markers for detection of pathogenic Escherichia coli strains belonging to serogroups O 138 and O 139.
Escherichia coli strains belonging to O-serogroup 138 and 139 are important as disease agents in pigs causing post-weaning diarrhea and edema disease. Several types of shiga toxin-producing O 138 and O 139 strains were isolated from diarrheic humans and from cattle and food of bovine origin. Serotyping is the current method for detection of O 138 and O 139 strains but its applicability can be l...

background: uropathogenic escherichia coli o- serogroups with their virulence factors are the most prevalent causes of utis. objectives: the present investigation was performed to study the virulence factors and o-serogroups profiles of upec isolated from iranian pediatric patients. patients and methods: this cross sectional investigation was performed on 100 urine samples collected from hospit...
متن کاملDirect detection of Shiga toxigenic Escherichia coli strains belonging to serogroups O111, O157, and O113 by multiplex PCR.
Shiga toxigenic Escherichia coli (STEC) strains are a diverse group of organisms associated with severe gastrointestinal and systemic diseases in humans. Within the STEC family, eae-positive STEC strains, particularly those belonging to serogroups O157 and O111, appear to have greater virulence for humans. However, in spite of being eae negative, STEC strains belonging to serogroup O113 have fr...
